Siri Analyses How You Use Your Device and Apps to Provide Personalised Suggestions and Better Search Results Using Local, On-Device Processing, and Syncs Across Your Devices with End-to-End Encryption Using iCloud
Siri uses local, on-device processing to learn how you use your devices and apps in order to personalise your experience. Using information stored on your device, such as your Safari browsing history, emails, messages, notifications and contacts, as well as information donated or contributed by other installed apps, Siri can suggest shortcuts and provide suggestions in searches share sheets, calendar, Look Up, Safari, apps and more. Suggestions may be used to personalise Apple services but are not stored on Apple servers or shared with other third-party apps. When you run a Siri-suggested shortcut, you are subject to the app’s terms and conditions and privacy policy.
Siri uses iCloud to sync personalisation across your Apple Devices using end-to-end encryption.
To Make Suggestions and Search Results More Relevant, Some Information Is Sent to Apple and Not Associated with You
When you use Siri Suggestions or Look Up, or type in Search, Spotlight, Safari search or #images search in Messages, any information sent to Apple does not identify you, and is associated with a 15-minute random, rotating, device-generated identifier. Your device may send information such as location, topics of interest (for example, cooking or football), your search queries, suggestions you have selected, apps you use and related device usage data to Apple. This information does not include search results that show files or content on your device. If you subscribe to music or video subscription services, the names of these services and the type of subscription may be sent to Apple. Your account name, number and password will not be sent to Apple.
This information is used to process your request and provide more relevant suggestions and search results, and is not linked to your Apple ID, email address or other data Apple may have from your use of other Apple services.
Aggregated information may be used to improve other Apple products and services. Common search queries may be shared with a web search engine to improve search results.
Search Engine Suggestions in Safari
Safari has a single field for searches and web addresses so you can browse the web from one convenient place. When Search Engine Suggestions are enabled, Safari will ask your selected search engine for suggestions based on what you’ve typed.
Preload Top Hit in Safari
With Preload Top Hit enabled, as soon as Safari determines a Top Hit based on your bookmarks and browsing history, Safari will begin loading the web page in the background. If you disable this option, the page will load normally.
